Joe Borowski has an ERA of 9.00, a WHIP of 1.73, and has no wins and one loss.

And yet he's been far and away better than Mariano Rivera. It's not even close.

Rivera, after his performance tonight, has a 12.15 ERA, a 1.95 WHIP, 1 win, 2 losses, and 0 saves. Zero. And 2 blown saves. This is the best closer in the history of the game. Incredible.

Before this season, his worst season as a closer was in 2000. That year, he went 7-4, with 36 saves and 5 blown saves, and an ERA of 2.86. That's his worst season. It's a career year for pretty much every other pitcher.

Last year he had a 1.80 ERA with 34 saves and 3 BS.

What happened?

Yeah, he's 37 years old, and yeah, there's still a lot of season for him to turn it around, but he's looked awful. Is he done?
